COMPARE THE COMPLICATION OF MINI WITH STANDARD PERCUTANEOUS NEPHROLITHOTOMY (PCNL) FOR THE TREATMENT OF SINGLE KIDNEY STONES
Main Article Content
Abstract
Objectives: To compare the complication of mini- with standard- percutaneous nephrolithotomy (PCNL) for the treatment of single kidney stones. Patients and Methods: The data of consecutive adult patients who underwent PCNL for the treatment of kidney stones, between December 2016 and December 2022 were retrospectively reviewed. All cases were performed in a prone position under fluoroscopic guidance. The nephrostomy tracts were dilatated to 26 F in standard-PCNL and to 16,6 F in mini-PCNL. A nephrostomy tube was inserted after PCNL. Study design: prospective cohort with comparison group. Complications of surgery were classified according to the Clavien-Dindo. Results: The study included 178 patients; 89 underwent standard-PCNL and 89 underwent mini-PCNL. The incidence (17,96% vs 24,27%, P = 0.048) and severity of complications were significantly lesser with mini-PCNL (P = 0.031). The complication transfusion rates did not differ between groups. Postoperative complications rates according to Clavien-Dindo classification was lesser with mini PCNL. Conclusions: The advantages of miniPCNL included a lesser incidence and severity of complications.
